Abstract (en)
Process of removing hydrogen cyanide and ammonia from synthesis gas obtained from partly oxidizing in a gasification reactor (2) a feed selected from the group including coal, oil or natural gas comprising supplying the synthesis gas in the presence of water to a reactor (5) containing hydrolysis catalyst; contacting the synthesis gas having an increased ammonia content from the reactor (5) in a sorption vessel (9) with regenerable sorption material to obtain ammonia-loaded sorption material and treated synthesis gas having a reduced content of nitrogen compounds, and withdrawing treated synthesis gas from the sorption vessel (9); and regenerating loaded sorption material to produce regenerated sorption material for use in step (b) and a regeneration off-gas enriched in ammonia, withdrawing regeneration off-gas enriched in ammonia from the sorption vessel (9), and introducing it into the gasification reactor (2).
